(54)	Gassing insulator assembly, conductor assembly and electrical switching apparatus employing the same

(57) A gassing insulator assembly for a line conductor assembly of an electrical switching apparatus is provided having a line conductor and first and second gassing insulator members. The insulator members are constructed from a gassing material. The first gassing insulator member is disposed near a first end of the line conductor and the second gassing insulator member is generally disposed between the line conductor and a cantilevered arc runner near a second end of the line conductor.
